PROCESS OF AS$EMBLING RADIATOR-CORE.

Patented Jan. 7, 1913.

Application filed October 16., 1911. Serial No. 654,964.

To all 'I/ lzom. it may concern Be it known that. I, Earn. CARL Fnncmncn able others skilled in the art to which it zip-'- pertains to make and use the same.

This invention relates to a process of assembling the elements constituting a ra diator, and has foitsobjcct to produce a method of constructing radiators which is more efiieient and less costly than the methods now in use.

To these ends the invention consists in the novel steps constituting my invention hereinafter more fully disclosed and particularly pointed out in the claims.

Referring to the accompanying drawings forming a part of this specification in which like numerals designate like parts'in all the views :Figure 1 is a plan viewo't a set of corrugated plates or distance pieces partially assembled to form my radiator; Fig. :2 is a side elevational view of the parts shown in Fig. 1, and illustrating the first stepsof my process; Fig. 3 is a side elevational view of a core after having been assembled and held in a frame; Fig. 4 is a diagrammatic vicw illus- [rating the dipping of the core shown in Fig. 3, into molten metal in order to secure the parts together: Fig. 5 is a side elevational View of the dipped core with the tubes in place; and, Fig. 3 is an enlarged detail sectional view of a portion of the completed radiator core.

The essence of this invention. as will appear below. consists in assembling in perfect form the core of the radiator. which is built up of distance pieces or tins, and before the tubes are pushcd through. i1'rc:-' ective of the shap or corrugations in the distance I pieces, or the contour of the tube which is to the tubes 4, fitting in the perforations 2, when the radiator is completed.

At present, as is well known, considerable trouble and expense is encmmtercd in building up the core provided with these air pas- 69 sages 5,'and in fitting the tubes at through the corrugated distance pieces forming the air passages. According to my present process, however, I employ rods or tubes 6 near each end of a nest of corrugated distance pieces 1 and thread said rods through the. perforations 2. forcing the said distancepieces one on top of the other withtheir portions 3 contacting with eachother, so as to form air passages 5, as best indicated in 79 Fig. 2; said reds or tubes 6 constituting rigid positioning guides for the several as:- semhlcd distance pieces. In this Way, the entire core of the radiator is built up to contain the proper number of distance pieces 7 or tins 1 and the parts are brought into perfect register. Rigid members 10 and 11, such as tlat plates or the usual top and hottcm headers. are then threaded on the positioning guides (3 and clamped in place on the core 9. as by a clamping frame 8; said rigid members 10 and '11 constituting means for confining the positioning guides 6 against umvomcnt relative to eaeh'other, thereb) preventing, longitudinal extension of the 35 corrugated distance pieces under pressure'.; The part. are next forced together until the required dimensions of the co'i'enreobtained, when one of the faces, such as the fi t for example, of the core this then dippedinto a bath of molten metal 12 and the parts firmly secured together along the front face only. The core is then removed from the bath 12 and the rear face is likewise dipped, thus securing the parts firmly together upon the rear face. After the core of corrugated pieces has thus received dippings uponits front. and rear faces, it constitutes a per; fectly rigid unimnd the tubular elements 4: can then readily be slid through their perforations 2 and a core provided with tubes completely finished.

It will thus be seen thattbe parts can ac-- cording to the disclosure above, be assem blcd in perfect form. and the core built up of distance pieces before the t'nbes are push-Gil through, irrespcct'it c of the particular shape or corrugations \iii the distance piror irrespective of the contour of thc a: which is used to circulate the water from the top to the bottom of the radiator.

'ikfter the core thus formed has receivedits tubes, a indicated in Figs. 5 and 6, it may then be secured to the shell or tank construct'1on of the-radiatorin-any nanner desired.

A convenient form of securing the same to said shell ,CODStILICtlOII ls'that disclosed no my co ending application Serial No. 654,963 filed ctober 16, 1911 and entitled radiators.

It is obvious that those skilled in the art' may vary the details of the steps above dissaid guides against moi/ement relative to each other, compressing said series of corrugated plates, and firmly connecting the longitudi nally-extending edges of 'such compressed series of corrugated plates.

2. The herein described process of formretest-o ing radiator, cores, which consists in threadmg rigid positioning guides through the end port-ions of a perforated series of flexible confining said transverselycorrugated plates, guides against movement relative to each other, compressing said series of corrugated pistes, and immersing the longitudinallyextending edges of such compressed series of corrugated plates in a molten bath. to secure said several plates together.

'3. The herein described process of forming radiator cores, which consists in threading rigid positioning guides through the end portions of a perforated series of flexible transversely-corrugatcd plates, confining said guides against movement relative to each other, compressing said series of corrugated plates, and threading a plurality of water tubes through. the perforations of such connected series of flexible corrugated plates in testimonywhereof, I aliix my signature, in presence of two Witnesses.
